P = 2(L + W)
P = 2(12 + 8)
P = 2(20)
P = 40.....so there is 40 meters of fence around the pool. If a post was placed every 2 meters, then u would have (40 / 2) = 20 posts <=
When you flip a coin twice, you have a 50/50 chance of it land on heads or tails.
The possible combinations for fliping a coin twice:

Answer:
a) The blue whale has about 200 times more mass
Step-by-step explanation:
(blue whale mass)/(cow mass) = (1.8×10^5 kg)/(9×10^2 kg)

... = 0.2×10^3
... = 200
The blue whale has about 200 times as much mass as a cow.
